Fits most 2007 and later H-D (except 10 and later Touring, 2012 Dyna/Softail/V-Rod), including 06 Dyna. The ViED(r) is our universal fuel management device. Its variable AFR design lets you set the fuel mixture for any H-D using the Bosch O2 sensor. A very simple adjustable AFR device for your bike requiring nothing more than a small screwdriver. This is based on our simple plug-n-play fuel management upgrade specifically designed for most Harley-Davidson bikes. Nightrider's unique patented design works with your existing OEM O2 sensor and ECM allowing richer fuel mixtures. Riders can quickly and simply richen the closed loop fuel mixture on your Twin Cam, Sportster or V-Rod engine from the stock 14.6:1 to a 14.3-13.7:1 AFR range.
The richer fuel mixture results in benefits that can include:
  • Cooler exhaust temperatures
  • Reduced engine temperatures
  • Improved throttle response
  • Less engine ping
  • Less low RPM engine surge
Nightrider's advanced patented design works inline with the narrow band O2 sensor and Delphi ECM to richen the fuel mixtures. Riders can quickly and simply richen the closed loop fuel mixture on your H-D engine from the stock 14.6:1 to 14.3-13.7:1 AFR. The ViED's can add up to 8% more fuel to the engine in closed loop operating mode than a similar unequipped vehicle. There is an indirect richening of open loop fuel mixture's through the learning mode or adaptive fuel value action, ensuring these richer 13.8-12.5:1 AFR's are also adjusted in heavy/full throttle situations.
Recommended for HD bikes with OEM emissions downloads. These include:

2008 Heritage Classic HD
Installation took about 10 minutes and is a true plug and play. The quality of connectors is very good. I really have not noticed any real difference in performance or heat coming from the motor. My bike is a 96CI Harley with V&H Longshots and S&S air cleaner/filter. I originally tried the 75% setting as recommended, but felt the bike didn’t run as crisp. I currently have them set at 50% both front and rear for the past 1000 miles. I might try 25% next. It only takes about one minute to adjust both VIEDs.

Works great, super easy install. I put it on my XR1200 with three-quarter inch drilled holes in the pipes. It cooled the motor right down. Now I have good Harley sound for $120 instead of $1000 for slip on mufflers and a power commander. Thanks Nightrider.

I attached my VIEDs after removing my baffles and tweeked them in tune and my make sounds badass everyone likes it because I have the "72" 1200 Sportster and couldn't do this until my warranty expired. Makes my neighbor's Streetglide sound like a minibike Lol

I purchased the VIED. 3 days later it was sitting in my mailbox. instructions were as easy to follow as they could be. the product seems well put together. Ground wire was included. However it was a bit short for the front O2 sensor to reach a good grounding point on my sportster. Not a real problem just had to use my imagination a bit. First ride after install and I did not notice the surging that I have been experiencing. I am still hearing the deceleration pop, but I have some adjustments that can still be made. I am happy so far. will see how it does after a week of commuting 40 miles to and from work. Thank you
